When a queue time satisfies a queuing threshold for a facility (e.g., a lounge, a venue, merchant location, any defined area, etc.), a notification of the queue time may be sent to a user device. A user interface of the user device may be used to provide credential information, and based on the credential information, display an indication of a digital instrument. A selection of the digital instrument may cause the user device to display a requirement for accessing the facility. Based on a confirmation of the requirement for accessing the facility and an indication that the queue time is less than the queuing threshold, the user device may display image data (e.g., a barcode, a matrix barcode, a quick response (QR) code, Radio Frequency Identification (RFID) tag, a marker, etc.) encoded with an access identifier that enables access to the facility.
